Windows 7 and Autodesk Inventor 2010

I installed inventor 2010 and when i try to run nothing happens, in the task manager it shows that inventor is loaded, but real the program didn't run. computer is thinking something and was waiting about 10 minutes but program didn't appear. In beta version 7077 everything was ok. Also i tried to run as administrator but the program didn't run too.

I just downloaded the 2010 version for Autodesk, but when I go to install it, it says it can't run on my current operating system. I read this thread and it sounded like the original poster actually got it installed, but I can't even do that. I tried changing the compatibility settings on Setup.exe...but when I run the set-up, it still says it can't run on my current OS.

Does anyone have any ideas? :/ Do I have to change the compatibility settings elsewhere too?
